The whitefly-transmitted tomato yellow-leaf curl gemini-virus (TYLCV) is a major pathogen of tomatoes. The wild tomato species Lycopersicon chilense, which is resistant to the virus, was crossed to the cultivated tomato, L. esculentum. The backcross-1 selfed (BC1S1) generation was inoculated and a symptomless plant was selected. This plant was analyzed(More)
The inheritance and linkage relationships of a gene for resistance to Fusarium oxysporum f. sp. lycopersici race 1 were analyzed. An interspecific hybrid between a resistant Lycopersicon pennellii and a susceptible L. esculentum was backcrossed to L. esculentum. The genotype of each backcross-1 (BC1) plant with respect to its Fusarium response was(More)
The dominant gene I2 confers on tomato (Lycopersicon esculentum) resistance against the fungus Fusarium oxysporum f. sp. lycopersici race 2. A restriction fragment length polymorphism (RFLP) marker, TG105, has recently been found to be tightly linked to I2. The potential for cloning this gene by a reverse genetics approach prompted us to describe in both(More)
Betty Friedan once said, " Aging is not 'lost youth' but a new stage of opportunity and strength. " We live in an information age that changes at a hectic pace, especially as we move into an always-on state of connectivity. As my parents got older, they found adapting to new technologies and using electronics in their daily life positively overwhelming. Not(More)
The locus, I2, which in tomato confers resistance against Fusarium oxysporum f. sp. lycopersici race 2, was introgressed into Lycopersicon esculentum from the wild species L. pimpinellifolium (P.I. 126915). We searched for restriction fragment length polymorphisms (RFLPs) between nearly isogenic lines (NILs) in clones that map to the region introgressed(More)
